发明名称 Programmable POR circuit with two switching thresholds
摘要 A power on reset circuit (POR) includes a first reset circuit for delivering a first reset signal when a supply voltage of the POR circuit is between a first low threshold and a first high threshold, and a second reset circuit for delivering a second reset signal when the supply voltage is between a second low threshold and a second high threshold. The second high threshold is less than the first high threshold. The POR circuit further includes at least one electrically erasable and programmable non-volatile memory cell. A delivery circuit outputs the first reset signal or the second reset based upon on whether the at least one electrically erasable and programmable non-volatile memory cell is in an erased or programmed state. The POR circuit has a threshold for outputting the first or second reset signal that is programmable according to the intended application.
